Abstract: A lockset includes symmetrically arranged front and rear handle assemblies, where the rear handle assembly includes a rear fixing base and a rear handle body. The rear fixing base is mounted on a door leaf. A connecting rod is configured to connect the front and rear assemblies. With a head facing rearward, a first fastening screw is provided outside the rear handle body to lock and connect the rear fixing base to the connecting rod. The rear handle body is provided with a through hole corresponding to the fastening screw. A movable cover body is configured to cover or expose the through hole for convenient operation. The rear handle body includes a supporting shaft and a housing. The housing and the cover body together form a gripping portion. The through hole is provided in the housing. An avoidance groove is provided on an outer side of the supporting shaft.

Abstract: A door lock with both manual and electric unlocking functions includes a lock body and a transmission rod. The lock body is provided with a latch for locking a door leaf. The transmission rod is in a transmission connection with the latch. When the transmission rod is manually or electrically driven to rotate forward or backward, the transmission rod is configured to drive the latch of the lock body to retract or extend, thereby achieving opening or closing of the door leaf. The door lock further includes a first housing, a rotating disc, and a rotating member. A misalignment device is arranged between the rotating disc and the rotating member. The misalignment device includes an idling area and a block, a controller, and a drive motor. The door lock further includes a positioning member fixedly arranged on the first housing.

Abstract: An electronic lock configured with internal and external modules includes a first module and a second module installed on inner and outer sides of a door leaf, respectively. The first module includes a first housing and a first circuit board accommodated in the first housing, and the second module includes a second housing and a second circuit board accommodated in the second housing. The first module further includes a first conductive contact arranged on the first circuit board and a first conductive post electrically signal-connected to the first conductive contact, and the second module further includes a second conductive contact arranged on the second circuit board and a second conductive post electrically signal-connected to the second conductive contact; and one of the first conductive post and the second conductive post is formed with an insertion cavity, and the other conductive post can be inserted into the insertion cavity.

Abstract: A lockset for locking a door leaf includes a first lock bolt, a second lock bolt, a first electric driver, and a lever component. The lever component is configured to tilt around a fulcrum, and the lever component comprises an inner end and an outer handle. The inner end of the lever component is drivingly connected to the second lock bolt. The outer handle of the lever component is configured to receive a pressing action of a hand. When the outer handle of the lever component is pressed, the lever component tilts, allowing the inner end to drive the second lock bolt to retract. The outer handle of the lever component is provided with a pickup device for picking up a biological signal of a finger. The pickup device is in electrical signal connection with a controller. The controller is configured to control the first electric driver to operate.
